Ms. Bankston went to Kennesaw Mountain one Saturday afternoon with her friend. Her friend was lazy and hated exercise, so she decided to take a shortcut beside the mountain. Ms. Bankston is always up for a challenge, so she decided to hike up the entiremountain! Unfortunately, her friend beat her to the car by almost an hour, and she was still full of energy. Ms. Bankston was exhausted. Who represents the enzyme in this analogy for a chemical reaction?

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
